Challenge overview

The Grounded CoMPaT Recognition (GCR) is a compositional 3D vision task that aims to collectively recognize and ground compositions of materials on parts of 3D objects. This task is based on the 3DCoMPaT dataset, a large-scale dataset composed of stylized 3D objects and associated 2D renderings.
We propose two variations of this task: GCR-Coarse and GCR-Fine, which are based on coarse-grained and fine-grained 3D segmentations of the 3DCoMPaT models.
We highly encourage participants of the challenge to enter and submit to both tracks of the challenge.

📊 Dataset

The 3DCoMPaT dataset for both challenge tracks is available through our download page.

📨 Submission

Submission will be made through the eval.ai platform.

📜 Rules

Here are the rules for the challenge:

• Submission Limit: Each participant is allowed to submit their solution a maximum of three times per day.
• Data Usage: Participants are not permitted to use any data other than the 3DCoMPaT data for training their models.
• Technical Report: Each participant must submit a technical report detailing their methods, which will be made public, in order to be eligible for any prizes or rewards.

🏆 Awards

Total prize pool: $3000. Teams are encouraged to particpate to both challenge tracks.

• 1st: $1300
• 2nd: $700

• 1st: $700
• 2nd: $300

These prizes are designed to motivate participants to put their best effort into the challenge and to reward those who perform exceptionally well. The challenge organizers hope that these prizes will encourage a high level of participation and help to drive innovation in the field of 3D computer vision. It should be noted that eligibility for these prizes is contingent on participants adhering to the rules of the challenge. Therefore, participants must submit their solutions in accordance with the rules and provide a technical report detailing their methods to be considered for any prizes or rewards.

🦜 Topics

Besides the CoMPaT challenge, the C3DV workshop also accepts papers in relation with compositional 3D vision. The workshop will include a poster and an oral session for related works. Topics of this workshop include but are not limited to:

• Deep learning methods for compositional 3D vision
• Self-supervised learning for compositional 3D vision
• Visual relationship detection in 3D scenes
• Zero-shot recognition/detection of compositional 3D visual concepts
• Novel problems in 3D vision and compositionality
• Text/composition to 3D generation
• Text/composition-based editing of 3D scenes/objects
• Language-guided 3D visual understanding (objects, relationships, ...)
• Transfer learning for compositional 3D Vision
• Multimodal pre-training for 3D understanding
• ...

The submitted 4-page abstracts will be peer-reviewed in CVPR format. Abstracts will be presented in the workshop poster session, and a portion of the accepted papers will be orally presented.
